DETAILED DESCRIPTION

While various embodiments are described herein, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible. Accordingly, the embodiments described herein are examples, not the only possible embodiments and implementations.

To implement no-threshold music creation and generate music to be enjoyed by ordinary users, there are the following two methods for generating music in the related technology: the first method is to convert a sound of a video into music, and the second method is to convert a speech recorded by a user into music. In the first method of generating music from a sound of a video, video data needs to be processed to extract sound data carried in the video, and then background music is added to the sound, thereby generating music to be enjoyed by a user. In the second method of generating music by using a speech, video data does not need to be processed, and music to be enjoyed by a user can be generated merely by synthesizing the speech with background music.

The foregoing technical solution for generating music can only add background music to a sound or speed of a video. In this music generating method, audio features of the sound or speech are not taken into consideration. Therefore, the generated music cannot be closely associated with music materials provided by a user. As a result, the generated music cannot match the music materials inputted by the user.

In some embodiments of this application, scenario recognition is performed on multiple images already inputted to a terminal, and respective description texts matching scenarios corresponding to the multiple images are generated. Then, keyword-based rhyme matching is performed on the description text matching the scenario corresponding to each image, and respective rhyming lyrics corresponding to the multiple images are generated. Next, the respective rhyming lyrics corresponding to the multiple images are converted into a speech. Finally, the speech is synthesized with preset background music to generate image music. In the embodiments of this application, image music can be generated as long as a terminal provides multiple images. Scenarios of the multiple images are recognized, description texts adaptive to the scenarios are obtained through automatic matching, and then rhymes are designed for the description texts of the scenarios. In this way, generated rhyming lyrics conform to music characteristics. Further, the rhyming lyrics are converted into a speech. Finally, the rhyming lyrics are synthesized with background music, thus forming a piece of image music. The rhyming lyrics in the image music are generated according to the images inputted to the terminal. Therefore, the outputted image music can be closely associated with image materials provided by a user. Thus, music that matches description texts of scenarios can be automatically generated by using inputted images.

The method and apparatus for generating music are described separately in the following. The embodiments of this application may be applied to a terminal. In the embodiments of this application, the terminal may be a personal computer (PC), a mobile terminal, a tablet computer, or the like capable of generating music.

An embodiment of a method for generating music according to this application may be specifically configured to generate, based on multiple images inputted by a user, music that matches description texts of the images. Referring to FIG. 1, a method for generating music provided in an embodiment of this application includes the following steps:

101: Perform scenario recognition on multiple images already inputted to a terminal, and generate respective description texts matching scenarios corresponding to the multiple images.

In this embodiment of this application, a user in a terminal may input multiple images for generating image music. The image music described in this embodiment of this application refers to rhythmic music adaptive the multiple images inputted by the user. The multiple images inputted in the terminal may be stored by the user in the terminal in advance, or may be acquired by the user in real time by using a camera of the terminal. For example, the multiple images may be acquired by the terminal after entering a photographing mode; or the multiple images may be obtained from a photo album of the terminal. Implementations of the multiple images already inputted to the terminal are not limited.

In this embodiment of this application, scenario recognition may be performed on the multiple images already inputted to the terminal, so as to recognize a scenario corresponding to each image. For example, classification of image scenarios may be implemented in many manners. For example, there are mainly four types of scenarios: scenery, people, food, and selfie. Image scenario recognition is performed according to pictures uploaded by a user. A scenario of each image is recognized, and texts that can describe scenarios corresponding to different images are obtained for each image through automatic matching. For example, scenario recognition is performed on the multiple images. For example, there are blue sky and birds on an image. In this case, a description text “

” (Chinese pinyin: xiao3 niao3 zai4 lan2 tian1 shang4 ao2 xiang2, meaning birds are flying in the blue sky) is automatically provided after scenario recognition.

In some embodiments of this application, step 101 of performing scenario recognition on multiple images already inputted to the terminal, and generating respective description texts matching scenarios corresponding to the multiple images includes the following steps:

A1: performing scenario recognition on the multiple images according to a deep learning neural network model to obtain recognized image features, and determining the respective scenarios corresponding to the multiple images according to the image features; and

A2: generating image descriptions according to the recognized image features and the respective scenarios corresponding to the multiple images, to obtain the respective description texts matching the scenarios corresponding to the multiple images.

In this embodiment of this application, scenario recognition may be performed on the multiple images by using a deep learning neural network model. The deep learning neural network model may also be referred to as a neural image annotation model. Image features may be recognized by using the deep learning neural network model, and the scenarios corresponding to the multiple images are determined according to the image features. Image recognition refers to a technology of processing, analyzing, and understanding images by using a computer, so as to recognize targets and objects of various different modes. Next, image descriptions are generated according to the recognized image features and the scenarios corresponding to the multiple images, to obtain the respective description texts matching the scenarios corresponding to the multiple images. An image scenario is recognized by using a deep learning neural network, and a related description text is automatically matched up with the scenario. Generating of image description means extracting, based on computer vision, an image feature by using a scenario and object class information as prior knowledge, and synergistically generating an image description sentence integrating the scenario and the object class.

102: Perform keyword-based rhyme matching on the description text that matches the scenario corresponding to each image, and generate respective rhyming lyrics corresponding to the multiple images.

In this embodiment of this application, the description text matching the scenario corresponding to each image may be generated through scenario recognition. The description text matching the scenario corresponding to each image is a basis for further generating lyrics. Rhymes of the text may be designed by using the description text matching the scenario of each image. Rhyming lyrics may be generated for each image. The rhyming lyrics refer to a verse that rhymes. The rhyming lyrics corresponding to each image may be a line of lyrics, or two or more lines of lyrics.

In some embodiments of this application, step 102 of performing keyword-based rhyme matching on the description text that matches the scenario corresponding to each image, and generating respective rhyming lyrics corresponding to the multiple images includes:

B1: obtaining, from the description text matching the scenario corresponding to each image, Chinese pinyin and a rhyme corresponding to a last word in the description text; and

B2: generating the rhyming lyrics corresponding to the multiple images according to the Chinese pinyin and the rhymes corresponding to the last words in the description texts, where the rhyming lyrics corresponding to each image have the same rhyme as the last word in the description text matching the scenario corresponding to the image.

In the description text matching the scenario corresponding to each image, Chinese pinyin and a rhyme corresponding to a last word in the description text may be obtained. In Chinese characters, there are less than 8000 commonly used Chinese characters. Therefore, a Pinyin table of commonly used Chinese characters may be generated in advance. An index is created according to the characters and is loaded into a memory. Pinyin of a Chinese character may be obtained as required. By searching a final table, it can be learned that there are 35 finals. All the finals may be put into an array, and sorted in descending order of final lengths. Then, a character string is sequentially compared with the finals, to obtain a rhyme corresponding to the last word. After the Chinese pinyin and the rhymes corresponding to the last words in the description texts are obtained, rhyming lyrics corresponding to the multiple images are generated based on the Chinese pinyin and rhymes corresponding to the last words in the description texts. The rhyming lyrics corresponding to each image have the same rhyme as the last word in the description text matching the scenario corresponding to the image. Therefore, the rhyme of the rhyming lyrics that can be generated may come from the rhyme of the last word in the description text. The design of the same rhyme can ensure that the generated rhyming lyrics corresponding to the multiple images have harmonious and uniform rhymes and sound catchier.

Further, in some embodiments of this application, step B2 of generating the rhyming lyrics corresponding to the multiple images according to the Chinese pinyin and the rhymes corresponding to the last words in the description texts includes:

B21: arranging all finals in the Chinese pinyin corresponding to the last words in the description texts;

B22: determining a final distribution rule according to all the finals arranged;

B23: determining the rhymes corresponding to the last words in the description texts from finals meeting the final distribution rule; and

B24: obtaining the rhyming lyrics corresponding to the multiple images from pre-generated lyrics patterns according to the scenarios corresponding to the multiple images and the rhymes corresponding to the scenarios, lyrics texts corresponding to multiple scenarios and multiple rhymes being preconfigured in the lyrics patterns.

A description text is matched up with the scenario corresponding to each image in the multiple images. The description texts each include a last word. Therefore, all possible finals may be arranged according to the Chinese pinyin of the multiple last words. For each final, different description text sentences corresponding to different scenarios are generated in advance as a lyrics pattern, a final distribution rule of last words in description texts is found by using data samples of multiple description texts. Finals that are distributed most frequently are found. The amount of data for such finals is increased, thereby determining which final is used as the rhyme. A lyrics pattern is searched for based on the rhyme selected according to the final distribution rule, and rhyming lyrics corresponding to the multiple images may be obtained by using the lyrics pattern.

An example is described as follows. In an example of generating rhyming lyrics of rap music, corresponding rap scripts may be generated as lyrics patterns for different rhymes of different scenarios, and more optional scripts are generated for a high-frequency rhyme. Then, a matching script is randomly selected according to a rhyme and a scenario, to generate rhyming lyrics of rap music. The same rap script is generated for the same rhyme. When some rhymes appear frequently, more lyrics patterns may be generated for the high-frequency rhymes, so that rhyming lyrics can be generated from multiple lyrics patterns.

Further, in some embodiments of this application, step B24 of obtaining the rhyming lyrics corresponding to the multiple images from pre-generated lyrics patterns according to the scenarios corresponding to the multiple images and the rhymes corresponding to the scenarios includes:

B241: generating image description lyrics according to the description text matching the scenario corresponding to each image;

B242: obtaining supplementary lyrics from the pre-generated lyrics patterns according to the scenarios corresponding to the multiple images and the rhymes corresponding to the scenarios; and

B243: synthesizing the image description lyrics with the supplementary lyrics, to obtain the rhyming lyrics.

Specifically, in the foregoing embodiment of this application, the description text matching the scenario corresponding to each image may be used as image description lyrics. The image description lyrics refer to lyrics from the description text. For example, the description text may be “

” (Chinese pinyin: xiao3 niao3 zai4 lan2 tian1 shang4 ao2 xiang2, meaning birds are flying in the blue sky). The description text may be used as image description lyrics. In step B242, supplementary lyrics may further be obtained. The supplementary lyrics and the image description lyrics may be generated simultaneously. The supplementary lyrics refer to lyrics obtained from a lyrics pattern. The supplementary lyrics and the image description lyrics may have the same rhyme. Finally, the image description lyrics and the supplementary lyrics may be synthesized to obtain the rhyming lyrics. For example, the description text may be supplemented in a rhyming manner. For example, if the image description lyrics are “

” (Chinese pinyin: xiao3 niao3 zai4 lan2 tian1 shang4 ao2 xiang2, meaning birds are flying in the blue sky), supplementary lyrics having the same rhyme as the image lyrics may be found from the lyrics patterns. The supplementary lyrics may be “

” (Chinese pinyin: cha4 bu5 duo1 de5 hao3, cha4 bu5 duo1 de5 zan4, meaning they are equally pretty). Therefore, the finally generated rhyming lyrics in this embodiment of this application may be:

;

,

(Chinese pinyin: xiao3 niao3 zai4 lan2 tian1 shang4 ao2 xiang2; cha4 bu5 duo1 de5 hao3, cha4 bu5 duo1 de5 zan4, meaning birds are flying in the blue sky, and they are equally pretty).

Further, in some embodiments of this application, step B242 of obtaining supplementary lyrics from the pre-generated lyrics patterns according to the scenarios corresponding to the multiple images and the rhymes corresponding to the scenarios includes:

obtaining a double-rhyme according to the image description lyrics; and

obtaining supplementary lyrics from the pre-generated lyrics patterns according to the scenarios corresponding to the multiple images and the double-rhyme corresponding to the scenarios.

In this embodiment of this application, when rhymes are obtained according to the image description lyrics, a double-rhyme may further be determined. A double-rhyme is a rhyme with two rhyming characters. The supplementary lyrics can be obtained from the lyrics patterns based on the scenarios and the double-rhyme. The supplementary lyrics are generated in a double-rhyme manner, so that the supplementary lyrics and the image description lyrics have the same double-rhyme.

103: Convert the respective rhyming lyrics corresponding to the multiple images into a speech.

In this embodiment of this application, after the rhyming lyrics corresponding to the multiple images are obtained, the rhyming lyrics may be converted from a text into a speech. Specifically, all the rhyming lyrics obtained in step 102 may be converted into a speech by means of txt-to-speech (TTS) conversion.

In some embodiments of this application, step 103 of multiple images converting the respective rhyming lyrics corresponding to the multiple images into a speech includes:

C1: performing text analysis on the respective rhyming lyrics corresponding to the multiple images, to obtain a text analysis result;

C2: extracting a linguistic feature from the text analysis result;

C3: performing phoneme-level duration prediction and adaptive duration adjustment according to the linguistic feature, to obtain a rhythm feature and a part-of-speech feature corresponding to the rhyming lyrics; and

C4: generating pronunciations by using a neural network model based on the linguistic feature as well as the rhythm feature and the part-of-speech feature that match the rhyming lyrics, to obtain the speech.

For the respective rhyming lyrics corresponding to each image, text analysis may be performed first, to provide information for subsequent feature extraction. The obtained text analysis result may be mainly used for generating pronunciations, predicting rhythms, predicting parts of speech, and the like. After the text analysis result is obtained, a linguistic feature is extracted from the result and is converted into an input vector of a neural network model. Next, phoneme-level duration prediction and adaptive duration adjustment may be performed by using a duration model. In this embodiment of this application, the generated rhyming lyrics are different from ordinary speaking, and are rhythmic. Therefore, the duration prediction result is adjusted adaptively, so that each character is on the beat while the original pronunciation remains unchanged. Finally, based on the linguistic feature as well as the rhythm feature and the part-of-speech feature that match the rhyming lyrics, pronunciations are generated by using the neural network model, to obtain the speech.

104: Synthesize the speech with preset background music to obtain image music.

In this embodiment of this application, after the rhyming lyrics are converted into the speech through step 103, the speech may include content of the rhyming lyrics. Then, the speech is combined with background music to generate final image music. The image music is obtained by synthesizing the rhyming lyrics compiled according to the multiple images inputted by the user with the background music. Therefore, when the image music is played, the user can hear a piece of rhythmic music with lyrics. For example, after rap rhyming lyrics are compiled according to multiple images, the rap rhyming lyrics are synthesized with rap background music, thus completing text-to-rap (TTR) conversion.

It can be learned from the illustration of this application in the foregoing embodiment that, first of all, scenario recognition is performed on multiple images already inputted to a terminal, and respective description texts matching scenarios corresponding to the multiple images are generated. Then, keyword-based rhyme matching is performed on the description text matching the scenario corresponding to each image, and respective rhyming lyrics corresponding to the multiple images are generated. Next, the respective rhyming lyrics corresponding to the multiple images are converted into a speech. Finally, the speech is synthesized with preset background music to generate image music. In this embodiment of this application, image music can be generated as long as a terminal provides multiple images. Scenarios of the multiple images are recognized, description texts adaptive to the scenarios are obtained through automatic matching, and then rhymes are designed for the description texts of the scenarios. In this way, generated rhyming lyrics conform to music characteristics. Further, the rhyming lyrics are converted into a speech. Finally, the rhyming lyrics are synthesized with background music, thus forming a piece of image music. The rhyming lyrics in the image music are generated according to the images inputted to the terminal. Therefore, the outputted image music can be closely associated with image materials provided by a user. Thus, music that matches description texts of scenarios can be automatically generated by using inputted images.

To facilitate better understanding and implementation of the foregoing solution in the embodiments of this application, a specific description is made below by using a corresponding application scenario as an example.

In this embodiment of this application, a song may be composed through Artificial Intelligence (AI), which is a prospective attempt and provides reference value for the application of AI in a larger scenario. In the following, generating of rap music is used as an example. TTR means conversion from a text into rap music, which mainly includes recognizing scenarios of multiple inputted images, then providing a description text conforming to each of the scenarios, designing rhymes of subtitles according to image content-based recognition, and finally converting the description texts for the scenarios into a speech through TTS. Subsequently, background music with a specific rhythm is added. The background music is synthesized with the text speech seamlessly to complete a piece of rap music. Finally, a piece of beautiful music with a rap characteristic is generated. In TTR, a scenario of any inputted image is recognized and a description text is provided. Through a series of processing, the description is converted into rap music. Composing songs by using AI is a prospective attempt and provides reference value for the application of AI in a larger scenario.

This embodiment of this application mainly includes recognizing scenarios of multiple inputted images, and finally combining the multiple inputted images into a music video (MV) accompanied with rap music. A user inputs multiple images from an applet on a mobile phone client. After the multiple images are uploaded, image scenarios are recognized by using a deep learning neural network model, and related description texts of the scenarios are obtained through automatic matching. Then, rhymes of the related description texts are designed through image content recognition. Finally, the rhyming texts are converted into a speech through a TTS technology.

FIG. 2 is a schematic flowchart of generating rap music according to an embodiment of this application. This system mainly includes four parts:

1. A user uploads or selects multiple images from a mobile phone client. The images inputted by the user are obtained.

2. Recognize image scenarios. Scenarios of the multiple inputted images are recognized, and related description texts are provided.

3. Design rhymes. Rhymes of the related description texts are designed.

4. Convert texts into a speech. The rhyming description texts are converted into a speech.

When a user submits multiple images on a mobile phone client, the multiple inputted images are recognized. Then, scenarios of the inputted images are recognized, and description texts adaptive to the scenarios are obtained through automatic matching. Next, rhymes are designed and supplemented according to the rhymes of the description texts. This is an AI algorithm. A description text is directly provided according to an inputted picture, that is, a scenario of the picture is determined directly. For example, there are birds flying in the blue sky, or someone is on the beach. Further, the texts are converted into a speech through TTS, and a piece of rap music is generated through subsequent processing.

Next, each part is separately described by way of example. FIG. 3 is a schematic diagram of uploading multiple images by a user from a mobile phone client. The user takes multiple pictures or selects multiple pictures in the mobile phone, and uploads the pictures from the mobile phone client. In an example of uploading images from a mobile phone client, when a user clicks an “upload image” button, two optional modes appear: one is a “photographing” mode, and the other is a mode of “selecting from a mobile phone photo album”. Multiple pictures may be selected and uploaded each time.

Next, image scenarios are recognized, and texts are matched automatically. Image scenarios are recognized according to the pictures uploaded by the user. A scenario of each image is recognized, and a text is matched up with each image automatically. Then, texts corresponding to all the images are connected. Text annotations are generated for the inputted images, and a success rate thereof can be maximized by training a neural image annotation model. Novel image descriptions can be generated. For example, the following annotation may be generated: a gray-suited man waves a stick, and a black-suited man looks on him. For another example, the following annotation may be generated: a bus “sits” beside a person.

Then, text rhyme design method provided in this embodiment of this application is illustrated. This application relates to the application field of generating an AI image item description, and in particular, to a keyword-based rhyme matching method. The main process is as follows:

1. Obtain text information generated from image descriptions, to obtain Chinese pinyin corresponding to Chinese characters, and rhymes.

2. Arrange all possible finals according to the Chinese pinyin, generate multiple description text sentences corresponding to different scenarios for each final in advance, implement double rhyming in the same sentence, and supplement the second sentence of lyrics in this manner. The pre-generating manner is as follows: listing all possible finals in Chinese pinyin. Rhyming lyrics corresponding to four classes of scenarios, that is, “scenery”, “people”, “selfie”, and “food”, are generated for each final.

3. Find a final distribution rule of description texts through data samples, find finals that are distributed most frequently, and increase the amount of data for such finals.

4. Generate and capture scenarios according to the image descriptions and the text descriptions, matching up rhyming materials with the scenarios according to finals of characters generated from the text descriptions.

5. Finally, technically present a complete composition with rhyming lyrics.

In this technical solution, pictures uploaded by a user are converted into texts based on an image recognition technology and an image description generating technology, and a random second sentence of lyrics is obtained through matching according to a final of the last word of the first sentence generated from an image description and an image scenario. Finally, rhyming lyrics are generated. Then, the rhyming lyrics are made into a song and sung through AI, thus forming a complete interaction process of uploading pictures by a user and composing lyrics and singing based on AI. Therefore, it is much more interactive and interesting. It means that multiple words in the lyrics can be used for matching.

First of all, image descriptions are generated and obtained. According to photos uploaded by a user, image description information is obtained by using an AI image description generating technology. A description sentence is obtained for each picture.

Then, Chinese pinyin is obtained. There are less than 8000 Chinese characters. A Pinyin table of commonly used Chinese characters is generated in advance. An index is created according to the characters and is loaded into a memory. When Pinyin of a Chinese character needs to be obtained, Pinyin can be quickly obtained within a time of O(1).

An example is described as follows:

a1,

Next, rhymes are obtained. It can be learned by searching the final table that, there are 35 finals. Using the Chinese character “

” (Pinyin: bian4) as an example, a three-letter final includes a compound final and a single final. For example, ian includes a final i and a final an. Therefore, the finals are obtained in the following sequence: three-letter final, compound final, and single final. In an implementation, all finals are put into an array and are sorted in descending order of final lengths. Then, a character string is sequentially compared with the finals.

Image description scenarios are obtained. Keywords in scenarios are obtained through matching according to texts of the image descriptions, so as to distinguish the corresponding scenarios. Currently, there are mainly four classes of scenarios: scenery, people, food, and selfie. The following are some of corresponding keywords.

Examples are described as follows: When the scenario is scenery, there may be multiple description texts, for example, scenery-sunshine, scenery-sea, scenery-rain, scenery-flower, and scenery-grass. When the scenario is people, there may be multiple description texts, for example, people-boy, and people-girl. When the scenario is food, there may be multiple description texts, for example, food-gourmet. When scenario is selfie, there may be multiple description texts, for example, selfie-picture, selfie-avartar.

Then, supplementary lyrics are obtained according to the scenarios and the rhymes. First of all, corresponding rap scripts are generated for different rhymes of different scenarios.

Finally, conversion from the texts to a speech is described by way of example. As shown in FIG. 4, text analysis is performed on the description texts, to provide information for subsequent feature extraction. The text analysis mainly includes: pronunciation generating, rhythm prediction, part-of-speech prediction, and the like. After the text analysis result is obtained, a linguistic feature is extracted from the result and is converted into an input vector of a neural network model. Phoneme-level duration prediction is performed by using a duration model. Phonemes are predicted by using the duration model, so that a better rhythm can be obtained. Rap music is different from ordinary speaking, and is rhythmic. Therefore, the duration prediction result is adjusted adaptively. Duration adaptation means automatic adjustment by using a neural network, so that each character is on the beat while the original pronunciation remains unchanged. A rap input refers to description texts. Acoustic feature prediction includes: rhythm prediction and part-of-speech prediction. A rap rhythm in a rap rhythm input is obtained through neural network prediction. Background music may have a relatively fast rhythm. Rap lyrics are obtained by recognizing scenarios of images to obtain description texts and designing rhymes of the description texts.

In this embodiment of this application, image music can be generated as long as a terminal provides multiple images. Scenarios of the multiple images are recognized, description texts adaptive to the scenarios are obtained through automatic matching, and then rhymes are designed for the description texts of the scenarios. In this way, generated rhyming lyrics conform to music characteristics. Further, the rhyming lyrics are converted into a speech. Finally, the rhyming lyrics are synthesized with background music, thus forming a piece of image music. The rhyming lyrics in the image music are generated according to the images inputted to the terminal. Therefore, the outputted image music can be closely associated with image materials provided by a user. Thus, music that matches description texts of scenarios can be automatically generated by using inputted images.

Optionally, the touch panel 1031 may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch position of the user, detects a signal generated by the touch operation, and transfers the signal to the touch controller. The touch controller receives the touch information from the touch detection apparatus, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 1080. Moreover, the touch controller can receive and execute a command sent from the processor 1080. In addition, the touch panel 1031 may be implemented by using various types, such as a resistive type, a capacitance type, an infrared type, and a surface acoustic wave type.

The described apparatus embodiments are merely exemplary. The units described as separate parts may be physically separated or not, and the parts displayed as units may or may not be physical units, that is, they may be located in one location or distributed on a plurality of network units. Some or all of the logical components may be selected according to actual needs to achieve the objectives of the solutions of the embodiments. In addition, in the accompanying drawings of the apparatus embodiments in this application, the connection relationships between logical components represent existence of communicative connections between the logical components, and may be physically implemented as one or more communication buses or signal cables. A person of ordinary skill in the art may understand and implement the embodiments without creative efforts.

According to the descriptions of the foregoing implementations, a person skilled in the art can clearly understand that, this application may be implemented with logic comprising a hardware/software combination. Moreover, specific hardware structures for implementing logic are diverse, which may be, for example, an analog circuit, a digital circuit, and a dedicated circuit. Alternatively or in addition, the logic may be stored in a non-transitory computer-readable storage medium such as a computer floppy disk, a USB flash disk, a removable hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc. The storage medium includes several instructions instructing a computer device (which may be a personal computer, a server, a network device, or the like) to perform the method in the embodiments of this application.

The logical components described herein may be hardware or a combination of hardware and software.

In some examples, each logical components may just be the portion of the memory or other physical memory that comprises instructions executable with the processor or other processor to implement the features of the corresponding logical component without the logical component including any other hardware. Because each logical component includes at least some hardware even when the included hardware comprises software, each logical component may be interchangeably referred to as a hardware logical component.

A second action may be said to be “in response to” a first action independent of whether the second action results directly or indirectly from the first action. The second action may occur at a substantially later time than the first action and still be in response to the first action. Similarly, the second action may be said to be in response to the first action even if intervening actions take place between the first action and the second action, and even if one or more of the intervening actions directly cause the second action to be performed. For example, a second action may be in response to a first action if the first action sets a flag and a third action later initiates the second action whenever the flag is set.
